SPECIFICATION forming part of Letters Patent No. 445,082, dated January 20, 1891. Application filed May 1, 1890. $eria1N0. 350,248. (No model.)

To aZZ whom it may concern:

Be it known that I, FRANK. RHIND, a citizen f the United States, residing at Meriden, New Haven county, Connecticut, have invented a new and useful Improvement in Lamp-Burners, of which the following is a specification.

My invention relates to burners adapted to consume hydrocarbon oil, and is intended to to simplify their construction and to increase the intensity of the light produced.

In the accompanying drawings, Figure 1 represents in vertical section a burner em bodying my invention. Fig. 2 is ahorizontal :5 section through the line on 00, Fig. 1. Fig. 3 is a vertical section of a duplex burner provided with my device; and Fig. 4: is a horizontal section through the line y y, Fig. 3.

The same letters refer to like parts in the several views.

A designates a burner-screw; B, a ratchetcap; 0, a perforated skirt; D, awiek-tube; E. a cone, dome, or deflector; c, a slot in the dome E; F, a foraminous partition.

2 5 All the parts of the burner except the foraminous partition F are well known in the art and may be of any desired form. Certain of these parts may be omitted and various other parts added, as may be necessary or advisable.

Burners of the class shown in Figs. 1 and 2 of the drawings are usually provided with a nearly horizontal perforated plate surrounding the wick-tube D and secured to the 3 5 skirt C near its upper edge. The office of this perforate plate is to check and divide the current of air passing through the coarser openings in the skirt C. As this plate is secured to the skirt or stationary part of the burner, as distinguished from the dome E, which is usually hinged or detaohably secured to the body or stationary part, it frequently becomes fouled and its perforations choked by wickchar, grease, and other foreign matters. Beside this, the plate acts as a cover to prevent the cleaning of the ratchet'cap B and the inner side of the skirt C, so that oil and finelydivided carbon collecting there are apt to take fire from the flame. In my device this perforate plate is eliminated and its place supplied by the funnel-shaped foraminous partition F, secured at its upper edge to the dome E, surrounding the slot 6, and at its lower end fitting around the wick-tube D. All the air which enters through the skirt C passes through the foraminations or reticulations in the partition F, so that eddies are prevented (and a steady constant supply of oxygen secured. It is evident that the partition F is removable with the dome E, and that such removal is necessary before the wick can be trimmed. Hence all the particles of charred wick and the like which are brushed from the wick fall directly on the ratchet-cap B or on the coarsely-perforated skirt C, whence they may be easily removed.

In Figs. 3 and 4; of the drawings I have shown a slight modification in shape of the partition F, which is equally advantageous with the form above described, and equally 7o applicable to the form of burner shown in the former figures. It is, however, peculiarly well adapted to the duplex burner here shown.

In this construction the partitionF is, as before, preferably secu red rigidly or detachably 7 5 to the dome E. It is, however, substantially in the form of an inverted-cone frustum instead of being oval in cross-section, as before shown, and extends downward substantially to the ratchet-cap B. Obviously the operation of the device will be as before explained.

I have spoken of the partition F as foraminous; but it is clear that it may be made of perforated metal or of equivalent woven Wire, as desired. It is also plain that the partition F may be made separately removable, if desired; but I much prefer to secure it either rigidly or detachably to the removable dome E. \Vhere in the claims I speak of a removable dome I desire to be understood as inelud- 9o ing a dome hinged or detachably secured to the body or stationary part of the burner.

I do not consider myself limited to the forms of construction herein shown or de scribed.

I am aware that lamp-burners have heretofore been made with a cylindric foraminous partition within the dome. In my device the partition is made of a smaller diameter at its lower than at its upper end. By this means I as the angle at which the partition meets the dome is enlarged and the flow of air through the upper rows of perforations much increased. In this way greater steadiness of the flame is secured. Beside this, the natural upward flow of air to the flame is less interfered with by a foraminous partition of an inverted conical or similar shape than by a vertical partition,so that a greater volu me of oxygen is supplied to the flame by my device.

\VhatI claim as my invention, and desire to secure by Letters Patent of the United States, is as follows:

' 1. In a 1amp-burner of the class described, the combination of a wick-tube, a removable dome, a slot in said dome, and a foraminous partition secured to and removable with said dome and surrounding said wick-tube, said able dome, a slot in said dome, and a forami-t nous partition secured to and removable with said dome and extending downward substantially to said ratchet-cap, said partition being of greater diameter at its upper than at its lower end, substantially as described.
